2 Claims. (Cl. 240-41.6)

This invention relates to automobiles headlights and an object of the invention is to eliminate glare from the headlight.

More particularly the invention has reference to that type of glare-eliminating headlights embodying an adjustable reflector; and the invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is a side elevational view of a headlight having our invention applied thereto,

Figure 2 is a longitudinal sectional view through the headlight further illustrating the application of the invention,

Figure 3 is a side elevational view of a reflector assembly,

Figure 4 is an enlarged transverse sectional view taken substantially on the line 4-4 of Figure 2,

Figure 5 is a side elevational view of a guide cylinder hereinafter more fully referred to, and

Figure 6 is an enlarged fragmentary transverse sectional view through the reflector assembly shown in Figure 3.

Referring to the drawings by reference numerals it will be seen that 5 indicates generally theshell of an automobile headlight. Ihe shell 5 is generally of well-known constructionand of any suitable design. In addition to the shell 5 the headlight is equipped with the usual lens 6 and retaining flange 1 therefor.

In accordance with the present invention there is placed within the shell 5 of the head- 05 light an elongated open-ended guide cylinder 8 which at the forward end thereof is provided with an outstanding flange 9 that is clamped be-- tween the rim of the lens 6 and the abutment flange ID of the shell 5 as clearly shown in Figure 40 2. It will thus be seen that the cylinder 8 is retained within the shell 5 in substantially the same manner as a reflector is conventionally retained in a headlight shell.

Having a sliding fit within the guide cylinder 45 8 is a reflector assembly indicated generally by the reference numeral II.

As shown the reflector assembly II, in the preferred embodiment of the invention comprises a parabolic reflector l2 behind which and spaced therefrom is a disk l3 that is connected to the rear of the reflector l2 through the medium of a tube 14 that forms a housing for an incandescent lamp socket l5. Socket I5 is adapted to accommodate an incandescent lamp or other suitable light source l6 as shown and in horizontal position with respect to the center of the reflector l2.

Reflector l2 and disk I3 flt snugly within the cylinder 8 with but sufficient clearance to permit sliding movement of the assembly longitudinally of the cylinder 8.

Untoward longitudinal shifting movement of the assembly is guarded against through the medium of a suitable spring element l6 mounted on the reflector I2 and having frictional engagement with the wall of. the cylinder 8 as clearly shown in Figures 2 and 3.

The disk I3 is braced with respect to the reflector l2 through the medium of a pair of oppositely disposed brace rods ll of insulating material.

Rods ll have a sliding fit within guide channels l8 provided therefor on the peripheral wall of the cylinder 8 as best shown in Figure 4.

Snugly fitted within the guide channels l8 are blocks or strips [9 of insulating material in which are embedded conductor strips 20.

Current to the contact strips 20 is conducted from any source of supply by a conductor 32.

Carried by the insulated brace bars or strips I! are conductor strips 2| that have sliding contact with the conductor strips 28, and these strips 2| are connected with the lamp socket 15 through the medium of wires 22 as also clearly shown in Figure 4. To accommodate the wires 22 disk [3 is provided with an aperture 23 as also best shown in Figure 4.

To slide the assembly II to advance or retract said assembly a Bowden wire or the like, operated from the instrument board or from any other convenient location, and indicated by the reference numeral 33 is employed and is connected at one end in a suitable manner to an apertured lug 34 provided therefor on the rear of the reflector l2 adjacent the bottom of the latter. To accommodate the wire 33 the shell 5 is provided with a tubular conduit 35; the cylinder 8 on the lower side thereof is provided with an elongated slot 36 and the disk l3 at the bottom thereof is provided with a radial slot 31 all of which will be clear from a study of Figures 2 and 4.

From the above it will be apparent that in the operation of the reflector for the purpose intended, when the assembly II is in the normally projected position shown in Figure 2 the beam or shaft of light is intensely projected on the road straight ahead of the vehicle. When, at the approach of an oncoming car, the operator desires to eliminate the glare in the eyes of the operator of the car that is being driven from an opposite direction, the operator of the car equipped with the invention exerts a pull on the Bowden wire 33 for causing the assembly I I to slide inwardly with respect to the forward end of the guide cylinder 8. With the assembly H in this inward position the rays of light will difiuse upon the road-bed directly in front of the vehicle but ouside the range of vision of the eyes of the driver of the oncoming vehicle. Manife'stly, a push exerted on the Bowden wire 33 will cause the assembly II to slide forwardly,

' to the normal position shown in Figure 2.

It is thought that a clear understanding of the construction, utility and advantage and op eration of an invention of this character will behad without a more detailed description.

Having thus described the invention what is claimed as new is:

1. In a lamp of the character described, a lamp casing, a horizontal open-ended guide cylinder arranged Within said casing and provided adjacent the bottom thereof with longitudinally extending guide channels, conductor strips arranged within said channels and insulated from said guide cylinder, an assembly slidably fitted within said guide cylinder and including a parabolic reflector having an incandescent lamp socketaccommodating tube extending rearward ly therefrom, a disk on the free end of said tube, bars of insulating material extending between said disk and reflector and having a sliding fit within the guide channels, conductor strips carried. by said insulated bars and having sliding contact with the first-mentioned conductor strips, a lampsocket arranged within said tube and electrically connected with the second named pair of conductor strips, an incandescent bulb mounted in the lamp socket and supported thereby in operative position to said reflector, and remote control means connected with said assembly for sliding the latter longitudinally of the guide tube to the desired position of adjustment.

2. In a lamp of the character described, a lamp casing, a horizontal open ended guide cylinder arranged within said casing and provided adjacent the bottom thereof with longitudinally extending guide channels, conductor strips arranged Within said channels and insulated from said guide cylinder, an assembly slidably fitted within said guide cylinder and including a parabolic reflector having an incandescent lamp socket accommodating tube extending rearwardly therefrom, bars of insulating material extending from said reflector and having a sliding fit within the guide channels, conductor strips carried by said insulating bars and having sliding contact with the first-mentioned conductor strips, a lamp socket arranged within said tube and electr'ically connected with the second-named pair of conductor strips, an incandescent bulb mounted in the lamp socket and supported thereby in operative position to said reflector, and remote control means connected with said assembly for sliding the latter longitudinally of the guide cylinder to the desired position of adjustment.
